Title: Protection system intended especially for software
IPC: G06F21/72
Filed: 1985-08-14
Abstract: This protection system consists in creating a coding by the combination of variables according to at least one boolean equation, this boolean equation being produced with the aid of an appropriate logic electronic circuit to the terminals of which are sent these same variables. In the case of protection of a program the variables are formed by the control and address bus bits of the computer in which this program is processed and the resultant code is read on the data bus. Each result is stored in a latch, the reading of which is only possible as a function of the result of another boolean equation and a TEST function is provided to prevent production of a clock signal validating the latches on switching on the computer and in order to lock the protection.

Title: Process and device for enriching the decanted phase in treatments for separation by flotation of oily or similar materials contained in a contaminated liquid
Inventor: PERIE RENE GASTON
IPC: B03D1/14
Filed: 1985-12-09
Abstract: To enrich the decanted phase in treatments for separation by flotation of oily or similar materials contained in contaminated water 7, a thick layer H of oil emulsion 22 is caused to form at the surface of the separation chamber 5, from which only the surface film 23, which is richer in oil, is removed. Advantageously, the desired layer thickness H is obtained by producing and continuously maintaining a determined distance DELTA between the maximum levels reached, on the one hand, by the oil emulsion 22 in the separation chamber 5 and, on the other hand, by the purified water 12 in the intermediate chamber 10. To do this, a funnel 24 is placed in the separation chamber 5, occupying a position such that a determined distance DELTA exists between the level of its overspill edge 25 and the maximum level reached by the purified water 12 in the intermediate chamber 10, means 26 to 29 making it possible to adjust the height position of the said funnel 24.

Title: Providing fuel-air mixt. acceleration enrichment for IC engine
Inventor: HOPPEL RAINER
IPC: F02D41/10
Filed: 1986-04-02
Abstract: Changes in the output voltage of a potentiometer coupled to the throttle flap are measured to detect transitions and to create the deman-led acceleration-enrichment area. This voltage is also used to create a time-limited fuel enrichment signal if necessary after matching characteristics. The output voltage from the potentiometer can be corrected using a non-linear device. A hot engine gets a richer mixture than a cold one. This change is linear with temp. Acceleration enrichment is limited for fast transition or for transitions leading to large throttle flap angles.
